An article search of dental literature up
to May 2010 in the databank PubMed using the keywords “bond strength”
and “dentin” or “enamel” yielded 2286 publications about adhesive bond
testing on dentin and 1360 about the same on enamel. In addition, 907
publications are listed in which the dye penetration test was used
(search words “microleakage” and “dentin”). Selected articles were
compared in terms of their test protocol and critically discussed in the
context of the existing literature. A comparison of laboratory data
with the results of clinical tests of adhesives will show the relevance
of the in vitro test methods
